Help dad let off steam every once in a while with the Urchin Sky Kniper—a 13-inch throwing knife that can also be used as a multitool.
The Kniper is good for chucking, sure. But beyond that, nearly every surface and edge of the high-carbon stainless steel blade and handle can be used for something. All told, there are 22 tools—from a Phillips-head screwdriver to a saw to a wire stripper. It even comes with a sundial printed on the outside of a universal hexhole.
If dad doesn’t like it, then ask him to give it to you.
